Correction: Bartoli et al. Preventive Diagnosis of Biological Colonization and Salt-Related Decay on the Frescoes of the “Oratorio dell’Annunziata” (Riofreddo, Latium, Italy) to Improve Conservation Plans. Appl. Sci. 2025, 15, 8762

In the original publication [1], Table 1 (S₁) was written incorrectly in the main text. There are three instances of “(Table 1 (S₁))” throughout the text that need to be changed to “Table S1”.

The following correction has been made to Section 2.2.3. Samples Collection, Paragraph 1:

A total of fifteen samples were obtained from different areas of the fresco (Figure 2), with the aim of characterizing both biological colonization and salt composition (Table S1).

The following correction has been made to Section 2.3. Laboratory Investigations, Paragraph 1:

Not all samples were investigated using the same analytical techniques (see Table S1).

The following correction has been made to Section 2.3.4. Ion Chromatography Analysis, Paragraph 1:

All samples (S₁–S₁₁, S_4b, S_5b, S_6b and Ss) were investigated with respect to their specific alteration phenomenology (Table S1).

The Supplementary Materials section was not included in the original publication, and it should appear as below:
